ETSI 5 ETSI TR 102 185 V1.2.1 (2001-05) 1 Scope The present document describes the objectives, structure and content of the Digital European Cordless Telecommunications (DECT) Data Services Profiles (DSPs), which define a set of profile standards
15、 for systems conforming to the DECT standard. They are a family of profile standards which build upon, and extend, each other, aimed at the general connection of terminals offering non-voice services between themselves or to other communications network, both public and private, via a DECT Fixed Par
16、t (FP). The present document also describes possible user scenarios in wireless mobile computing. These scenarios have formed the guidelines of the DECT DSPs. 2 Re fe re nces For the purposes of this Technical Report (TR) the following references apply: il ETSI EN 300 175-1: “Digital Enhanced Cordle

34、eless data communication. The purpose of these clauses is to give a background for user requirements and an introduction to the services and facilities that the DECT DSPs are aiming to support. 4.1 Mu It i m ed i a resident i al cord I ess Figure 1 shows a typical multimedia residential cordless app

The FP supports DECT voice terminals as well as DECT data terminals. If a call is set-up with a DECT data terminal, the internet can be accessed with a modem bui
36、ld into the FP. Typical data terminals in this application are: devices for accessing the internet; plugs which can be connected to standard PCs.

37、Virtual USB USB V.24 interface DPRS V.24 interface I I PP Typical data terminals in this application are: devices for accessing the internet; plugs which can be connected to standard PCs; bar-code readers. Wireless Local Area Network (LAN) A wireless LAN can extend or even substitute for a standard
38、wired LAN. The wireless LAN will function as a wired LAN does, using the same network protocols as wired LANs today (e.g. TCPAP). The users of wireless LANs can be organizations which: 0 need local terminal mobility; 0 need to be flexible in re-configuring their LAN; require a temporary LAN; are sit
39、uated in buildings where the installation of extra cabling is costly, disruptive or forbidden (such as historic buildings or those containing asbestos). Relevant applications will include those running on most LANs today (such as Office productivity tools, Internet browsers and e-mail applications)
40、and new applications specially designed for mobile terminals. The new opportunities offered by cordless terminal mobility will create brand new markets for information technology. It is extremely important that the wireless LAN is at least as dependable as a wired LAN. The reason for this is the dep
41、endency placed on LANs to work without failure in modern businesses. This means that the wireless LAN has to give the user a very high degree of confidence that it will avoid corruption of data and deliver a minimum level of throughput in all places where coverage is defined. ETSI 9 ETSI TR 102 185
42、V1.2.1 (2001-05) The addition of data services to a wireless PABX can offer value added services with very little additional complexity and can use the same installed set of base stations that already provide speech services. In particular, services such as fax and access to files stored on a LAN ca
43、n be provided. There is also the possibility of adding new cordless services such as cordless data entry and inventory control. An infrastructure that can offer both wireless speech and data services over the same infrastructure will offer extremely flexible and cost effective solutions to users for
44、 whom staff mobility is a requirement. W Figure 3 Another important scenario is when roaming between networks such as LANs or PABXs is needed, the user is allowed to continue to use his network identity or “address“ when moving between different networks. For instance, this would make it possible fo
45、r an employee of a large company to travel from the main office to a branch office, still being connected via the local networks to his/her home networks, receiving electronic mail and retrieving documents from his or her home server. In this scenario, additional functions such as roaming and authen
46、tication procedures have to be supported by the wireless networks. The scope of the mobility offered to the user is increased in this scenario. Therefore, applications, which are specially designed for mobile terminals, will be able to offer even greater added value than in the scenario in clause 4.
47、1.1. Roaming between wireless LANs/PABXs allows users speech and data services to be available and automatically re-routed to them as they move between different LAN/PABX sites either within one company or between several companies. This can make possible enormous cost savings to user organizations
48、as the productivity of their employees is increased. 4.4 SMS messaging on a Private Automatic Branch Exchange (PABX) The Short Message Service Mobile Terminated (SMS-MT) can be used to send messages to individual DECT terminals, or to a group of DECT terminals. Typical applications are: contacting p
49、eople with a busy meeting schedule; patient alarms in hospitals, which send a pre-programmed message directly to the health care worker in charge; sensors in factory equipment, which send a pre-programmed message directly to an engineer. ETSI 10 ETSI TR 102 185 V1.2.1 (2001-05) The Short Message Service Mobile Originated (SMS-MO) can be used to send messages from an individual DECT terminal to an operator. Typical applications are: a DECT terminal can be equipped with a push button or non-movement alam. In case of an emergency, a message will be send to on operato
